Next‐Generation Glutamine Synthetase Expression Vector for Therapeutic Protein Manufacturing Using CHO Cells

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT The glutamine synthetase expression system is widely used for therapeutic protein biomanufacturing in Chinese hamster ovary (CHO) cells. Here, we present the design of an enhanced glutamine synthetase vector for generating CHOK1SV GS‐KO stable pools that produce recombinant proteins at multigram‐per‐liter levels. We first developed a synthetic

C─S Bond Formation of Aryl Germanes

open access: yesAngewandte Chemie, Volume 138, Issue 41, 5 October 2026.
Site‐selective C─S bond formation of aryl germanes, even in the presences of other functional groups such as silane or boron derivatives, is described. The protocol operates under metal‐free conditions at room temperature without the need of inert atmosphere.

A toxicogenomics approach reveals characteristics supporting the honey bee (Apis mellifera L.) safety profile of the butenolide insecticide flupyradifurone

open access: yesEcotoxicology and Environmental Safety, 2021
Flupyradifurone, a novel butenolide insecticide, selectively targets insect nicotinic acetylcholine receptors (nAChRs), comparable to structurally different insecticidal chemotypes such as neonicotinoids and sulfoximines.

Biomimetic N‐cyano sulfoximine–thiazole ligation for antibody–drug conjugate assembly

open access: yesBulletin of the Korean Chemical Society, EarlyView.
Biomimetic N‐cyano sulfoximine–thiazole ligation is applied for the first time to antibody–drug conjugate assembly. Installation of a sulfoximine handle on trastuzumab followed by ligation with a cysteine‐functionalized payload affords model ADCs with tunable drug‐to‐antibody ratios of 2–8 under mild aqueous conditions.

Thermal Nickel‐Catalyzed N‐Arylation of Sulfonimidamides With (Hetero)aryl Chlorides Enabled by PAd‐DalPhos Ligation

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
The nickel‐catalyzed S═NH N‐arylation of sulfonimidamides is described, with useful demonstrated substrate scope involving inexpensive and widely available (hetero)aryl chloride reaction partners, including the active pharmaceutical ingredient chlorpromazine.

Photochemistry of N‐Phenyl Benzonaphthothiophene and Dinaphthothiophene Sulfoximines

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
The sequential photorelease of nitrenes and atomic oxygen [O(3P)] from N‑phenyl benzonaphthothiophene and dinaphthothiophene sulfoximines is a rare photochemical phenomenon in which two reactive intermediates can be released from a single chromophore. The sequential photorelease of nitrenes and atomic oxygen [O(3P)] is a rare photochemical phenomenon ...

Synthesis and Computational Simulation of New Phosphorilated Sulfoximines with Insecticidal Activity

open access: yesMolecules, 2000
New organophosphorus insecticides of dialkylsulphoximines derived with activity upon acetylcholinesterase were synthesized. The obtained compounds were characterized by NMR and IR, and anticholinesterase activity and toxicity was measured.

Copper-Mediated Cross-Coupling Reactions of N-Unsubstituted Sulfoximines and Aryl Halides

open access: yes, 2016
Copper-mediated cross-coupling reactions of sulfoximines with aryl iodides and aryl bromides provide N-arylated sulfoximines in high yields. The method is complementary to the known palladium-catalyzed N-arylation and allows the preparation of N-arylated

Functionalizations of sulfoximines and mechanochemistry studies

open access: yes, 2022
Sulfoximines, the mono-aza analogs of sulfones, have attracted the attention of many chemists in the last few decades. Since the first discovery of MSO. Sulfoximines have been extensively used in agricultural science, asymmetric synthesis, and medicinal ...

Temporal variation in susceptibility of Euschistus heros (Hemiptera: Pentatomidae) to pyrethroids and neonicotinoids, and spatial patterns of control failure likelihood in southern Brazil

open access: yesPest Management Science, EarlyView.
Monitoring of Euschistus heros populations in Rio Grande do Sul, Brazil, from 2017 to 2026 revealed declining susceptibility to pyrethroids and neonicotinoids. Reduced susceptibility to λ‐cyhalothrin and acetamiprid persisted, whereas declines in susceptibility to bifenthrin, imidacloprid and certain pre‐formulated mixtures emerged more recently ...
